Detecting an Alarm Condition

If there is an alarm condition, the alarm icon comes on steadily and the alarm code is displayed. If present and enabled, the alarm relay is also activated.

NOTE: If alarm exclusion timings are in progress, the alarm is not signaled.

All active alarms, except those relating to probe error, are listed in the ALr folder within the ClimaSys cooling unit status menu.

Silencing an Alarm

Press any key or use the menu function: the alarm icon flashes, and the alarm relay is de-energized.

The alarm icon goes off when the alarm condition disappears.
